Disclosed herein is a housing for a disk of filter material. The housing includes two disk-shaped parts. One of the housing parts includes a radially-inwardly facing cylindrical surface for locating a filter disk. The other housing part includes a radially-outwardly facing cylindrical surface. The two cylindrical surfaces telescope together during assembly and serve to locate the housing parts relative to one another in directions parallel to the general plane of a filter disk in the housing. The radially inwardly facing cylindrical surface serves to locate a filter disk during assemble. Radially inwardly of the cylindrical surfaces is resilient means for engaging and squeezing the annular peripheral margin of the filter disk for at least partially preventing material being filtered passing radially outwardly of the filter disk and for totally preventing material bypassing the filter disk. Radially outwardly of the cylindrical surfaces is second resilient means providing a seal between the two housing parts for preventing any leakage out of the filter disk, passing to the exterior of the housing.
